The oldest lunar features are the lunar highlands. This is mainly determined by looking at the number of impact craters that the different areas of the moon have. The longer that a feature has been around, the more time it has had to be hit by the meteors that leave impact craters.

Which features of the Moon are the oldest?
Answer and Explanation: The Lunar Highlands are the oldest features of our moon. These highlands are about four billion years old (the moon itself is considered to be about 4.4 billion years old) and were created by a huge crater after the impact of a large object, most likely a meteor, with the moon.
How old are the oldest areas of the Moon?
Oldest Moon Rocks. The Apollo missions sampled ancient lunar crustal rocks. These rocks are about 4.5 billion years old, indicating that parts of the Moon’s crust solidified soon after the Moon formed.
Is the Moon the oldest?
A new study of Apollo lunar rocks suggests that the moon is older than anyone believed. The moon, researchers now say, likely formed about 50 million years after the solar system did, which is much earlier than the previous estimate of 150 million years after solar-system formation.
Are the darker parts of the Moon older?
The solar wind tends to darken the moon minerals. This is why the younger craters have bright rays and the older craters appear much darker.
Which region of the moon is older?
In contrast the surface of the Moon is much older, with much more cratering. Further, different parts of the surface of the Moon exhibit different amounts of cratering and therefore are of different ages: the maria are younger than the highlands, because they have fewer craters.
Which Moon has the oldest surface?
Callisto’s
Callisto’s rocky, icy surface is the oldest and most heavily cratered in our solar system. The surface is about 4 billion years old and it’s been pummeled, likely by comets and asteroids.
Why is the moon older?
The Moon likely formed in the aftermath of a giant collision between a Mars-sized planetary body and the early Earth. Over time, the Moon accreted from the cloud of material blasted into Earth’s orbit. The newborn Moon was covered in a magma ocean, which formed different types of rocks as it cooled.
What is the oldest space?
Astronomers have discovered what may be the oldest and most distant galaxy ever observed. The galaxy, called HD1, dates from a bit more than 300 million years after the Big Bang that marked the origin of the universe some 13.8 billion years ago, researchers said on Thursday.
Which region of the moon is the youngest?
lunar maria
The lunar maria (or plains), which were formed between 3.1 and 3.9 billion years ago, are the youngest geologic units on the lunar surface, except for more recent impact craters.
What is the oldest name for the moon?
Selene, (Greek: “Moon”) Latin Luna, in Greek and Roman religion, the personification of the moon as a goddess.
Why is the moon older than the Earth?
That’s because the moon likely formed after a rogue, Mars-sized planet collided with the young Earth in the early days of the solar system. The debris from this giant impact (mostly bits of Earth’s pulverized mantle) sprayed into the atmosphere, eventually coalescing into the round, rocky satellite we know and love.
How old is the moon and how was it formed?
The most widely accepted origin explanation posits that the Moon formed 4.51 billion years ago, not long after Earth, out of the debris from a giant impact between the planet and a hypothesized Mars-sized body called Theia. It then receded to a wider orbit because of tidal interaction with the Earth.
Why do you age slower on the moon?
Time passes about 0.66 parts per billion faster on the Moon than on Earth, due to not being in as strong a gravity field.
Why are some parts of the moon darker than others?
The phases, or changing appearance, of the Moon depend on its position relative to the position of the Sun. When the Moon is between the Sun and the Earth, the side of the Moon facing the Earth is dark.
When did the moon turn black?
A Black Moon will appear for you on April 30, 2022, as the second new Moon in the month of April.
How old is the oldest crater on the moon?
It is the largest, oldest, and deepest basin recognized on the Moon. It is estimated that it was formed 4.2 to 4.3 billion years ago, during the Pre-Nectarian epoch. It was named for two features on opposite sides of the basin: the lunar South Pole at one end and the crater Aitken on the northern end.
Which planet has the oldest surface?
Mercury
Mercury, Venus, Earth, and Mars are terrestrial (rocky) planets. Among these, Mercury is an extreme: the smallest, the densest (after correcting for self-compression), the one with the oldest surface, the one with the largest daily variations in surface temperature, and the least explored.
Why are rocks on moon older?
The Moon has essentially no erosion and no plate tectonics. There is nothing happening to do much to alter the rocks on the Moon, whereas many different processes on Earth are destroying old rocks and making new ones.
How old is the moon exactly?
4.51 billion years ago
The moon is a very old soul, it turns out. A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
How old is moon today?
Today’s Moon is 99% of Full and 13 days old.
